Reston, Va.-based LightSquared revealed Thursday that it has sent a new letter to the FCC blaming the GPS industry for the fact that GPS interference is even happening in the first place:
"Had the GPS industry complied with DoD’s [Department of Defense] recommended filtering standards for GPS receivers, there would be no issue with LightSquared’s operations in the lower portion of its downlink band," LightSquared's Executive Vice President for Regulatory Affairs & Public Policy Jeff Carlisle stated in the FCC filing.
LightSquared is trying to deploy a hybrid satellite and Long Term Evolution (LTE) network in L-Band spectrum across the U.S. The problem is that GPS receivers operate in the band next door and are used to much weaker triangulation signals from satellites in space. So, in tests, some have been shown to pick up signals from the terrestrial L-Band LightSquared base stations, making GPS less accurate or useless.
After finishing testing, LightSquared offered to move down the L-band frequencies to help alleviate the problem. Some in the GPS industry say, however, they will still suffer from interference.
So now the gloves are evidently off: Compare the tone of LightSquared's new letter with Carlisle's earlier talk about working with the industry on filtering.
Why this matters LightSquared can't launch anything until the FCC says the GPS issue is resolved. And it has inked a massive deal to start LTE service in 2012, so, the race is on. (See Sprint's $13.5B Jump to LTE With LightSquared.)
